Refractory angina pectoris carries a favourable prognosis: A three-year follow-up of 150 patients
Bibliographic record
Abstract
OBJECTIVE: To investigate the three-year prognosis in refractory angina pectoris. PATIENTS: Two hundred and forty three patients were screened at six European university hospitals for a gene therapy trial. In 150 patients refractory angina pectoris could be confirmed. Vital status was assessed after a mean of 33 months. RESULTS: At baseline, mean age was 63+/-9 years and mean LVEF was 52+/-12%. In 61% there was a history of myocardial infarction and 83% had previously been revascularised. Mortality was 5.5% at one year and 13.5% at three years. New revascularisation options were found in 9.5% of the 243 screened patients at baseline coronary angiography. Additionally, in 6% of the trial patients the protocol-specified angiogram after three months revealed new significant stenosis, which was treated by percutaneous intervention. CONCLUSIONS: Annual mortality in refractory angina pectoris seems higher than in stable angina pectoris in general, but substantially lower than after myocardial infarction. The "refractoriness" of these patients should be re-evaluated regularly, as new revascularisation options often occur.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
